That appears to be missing a couple of == at the end to decode to
Deployment\temp\Modifi

If you know that the text encoded is valid XML character data then your 
system may have an extension function to decode it

http://www.saxonica.com/documentation/extensions/functions/base64binarytostring.html

(or it wouldn't be too hard to write the decoder in xslt) but in general 
base64 can encode binary data that includes byte sequences  not legal in 
XML text encodings so in that case you'd have to decide what to do (the 
usual way of encoding such things in xml is to base64 encode them....
